33
34 1) umul_ppmm(high_prod, low_prod, multipler, multiplicand)
35 multiplies two u32 integers MULTIPLER and MULTIPLICAND,
36 and generates a two-part u32 product in HIGH_PROD and
37 LOW_PROD.
38
39 2) __umulsidi3(a,b) multiplies two u32 integers A and B,
40 and returns a u64 product. This is just a variant of umul_ppmm.
41
42 3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
43 denominator) divides a two-word unsigned integer, composed by the
44 integers HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and
45 places the quotient in QUOTIENT and the remainder in REMAINDER.
46 HIGH_NUMERATOR must be less than DENOMINATOR for correct operation.
47 If, in addition, the most significant bit of DENOMINATOR must be 1,
48 then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1.
49
50 4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
51 denominator). Like udiv_qrnnd but the numbers are signed. The
52 quotient is rounded towards 0.
53
54 5) count_leading_zeros(count, x) counts the number of zero-bits from
55 the msb to the first non-zero bit. This is the number of steps X
56 needs to be shifted left to set the msb. Undefined for X == 0.
57
58 6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
59 high_addend_2, low_addend_2) adds two two-word unsigned integers,
60 composed by HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and
61 LOW_ADDEND_2 respectively. The result is placed in HIGH_SUM and
62 LOW_SUM. Overflow (i.e. carry out) is not stored anywhere, and is
63 lost.
64
65 7) sub_ddmmss(high_difference, low_difference, high_minuend,
66 low_minuend, high_subtrahend, low_subtrahend) subtracts two
67 two-word unsigned integers, composed by HIGH_MINUEND_1 and
68 LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and LOW_SUBTRAHEND_2
69 respectively. The result is placed in HIGH_DIFFERENCE and
70 LOW_DIFFERENCE. Overflow (i.e. carry out) is not stored anywhere,
71 and is lost.
72
73 If any of these macros are left undefined for a particular CPU,
74 C macros are used. */
